BATH-SPRAY.

Application filed June 30, 1919, Serial No. 307,618.

To all whom it may concern;

Be it known that I, JEROME J. DONOVAN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Bath- Sprays, of which the following is a specification.

My invention is a pulsating and intermittent bath spray.

Referring to the annexed drawing which forms a part of this specification:

Figure 1 is a side view of a bath spray embodying my invention.

Fig. 2 is a front view of said bath spray.

Fig. 3 is an enlarged side view of the spray head and union for coupling the head to a spray fixture.

Fig. 4; is an outer end view of one member of said union.

Fig. 5 is a longitudinal section of said union.

Fig. 6 is an inner end view of the other member of said union.

Fig. 7 is a plan of the spiral guide of the rotary interrupting spray valve. I

Fig. 8 is a side view of said spiral guide.

Fig. 9 is a plan of the rotary interrupting valve wheel.

Fig. 10 is a side view of said wheel.

In the drawing, 1 indicates a bath tub hot and cold faucet to which is connected a bath fixture 2. A spray head 3 is connected to the upper end of the fixture 2-by a union 1 and a spray head 5 is connectcd to the lower portion of the fixture also by a union 4:. The union includes an externally threaded sleeve 5 and an externally and internally threaded nut 6 into which screws one end of the sleeve 5. The other end of the sleeve 5 screws into the fixture 2 while the nut 6 screws into the spray head 3 or 5. i The nut 6 has an end wall 7 in which are ports 8. In the sleeve 5 is mounted a spiral guide 9 by means of lugs 10 extending from the edges thereof and resting in recesses 11 in the inner end of sleeve 5. Extending from the inner end of the guide 9 is a pin 12 on which is journaled a rotary interrupting valve wheel 13. Said valve wheel is formed with radial blades 14 which converge to an edge adjacent the inner end of guide 9 so as to offer Specification of Letters Patent.

little resistance to the water flowing through the union and to facilitate the rotation of the wheel by the water passing through it. On the end of the hub of the wheel 13 is a ournal 15 which turns in a bearing 16 in the wall 7 and prevents the blades of the wheel from being forced into engagement with the wall 7 by the water and jamming the wheel.

The water in passing through the union is glven a spiral direction by the guide 9 and rotates the wheel 13 which alternately closes and opens the ports 8 and interrupts the flow of water without destroying the continuity of its stream, thus giving the water passing from the spray head a pulsatin action.

aving described my invention, I claim:

1. A union formed in two sections, a spiral guide mounted in one of said sections, the other section having ports, and a valve wheel mounted in said other section to rotate past said ports under the influence of the water delivered from said guide.

2. A union formed in two sections, a spiral guide in one of said sections, the other section having ports, a pin on said spiral guide, a valve wheel journaled on said pin, adapted to rotate past said ports, a journal on the far end of the hub of said wheel, and a bearing in said other section in which said journal turns.

8. A union formed in two sections, a spiral guide in one of said sections, said section having recesses in its inner end, lugs on the inner end of said guide fitting in said recesses, the other section having ports and a valve wheel mounted in the other section for rotating past said ports.

4. A union formed in two sections, a
